Investigators say Brisbois was on a work-release program in May when he was left unsupervised at the East Kingston Police Department, where he found and used heroin and marijuana. He is accused of taking heroin into the Rockingham County House of Corrections.

Brisbois is also accused of breaking into a patrolman's locker, where he had access to his uniform and duty belt, including a handgun, stun gun and handcuffs.

The investigation also includes allegations that Brisbois drove around in a cruiser.
